Abstract:
This paper aims to introduce the synthesis and characterization of some useful thermo electric pellets in order to determine their ability to convert waste heat into electricity. The thermo electric pellets of Bi2Pb3, Bi2Te3 and Pb2Te3 in cylindrical dimensions are prepared by 15 mm mixture of different compositions. The research work explores the facts that how such kind of the semiconducting materials can be utilized as thermo-electric power generation elements. The performance of these pellets analyzed not only in the normal mode but also under the effect of electric and magnetic fields, which can exist already or applied in the condition of their operation. Thermo-emf generation is carried out in the normal mode and under the influence of applied electric and magnetic fields of different magnitudes in the temperature range of 190 °C. Hence, the paper is an outlet of the waste heat utilization with the influence of electric or magnetic field towards their conversion of waste heat into electricity by special sized thermoelectric pellets and the suitable chemical method of their preparation.

Abstract:
Empty fruit bunches (EFB) is a good lingo-cellulosic biomass to produce bio-ethanol, to generate electricity by using chemical or thermo-chemical conversion processes respectively. It is one of the potential renewable energy sources to reduce the dependency on fossil fuels and environment pollution. It is found that about 6% of diesel fuel can be saved by using palm oil EFB based converted bio-ethanol. By using thermo-chemical conversion of palm oil EFB, about 5% electrical energy demands can be fulfilled.

Abstract:
Thermo-electro-mechanical behaviour of the nano-sized structures is analysed by the finite element method (FEM). The mechanical response of the nano-sized structures cannot be modelled with classical continuum theories due to the size effect phenomenon. The strain gradient theory with one length scale parameter has been applied to study size effect phenomenon. The coupled theory of thermo-electricity has been used together with strain gradient theory of elasticity. The governing equations have been derived and incorporated into the commercial software Comsol via weak form module. The influence of the length scale parameter on mechanical response of the structures is investigated by some numerical examples.

Abstract:
The aim of this study is the thermo-economic assessments of an integrated solar combined cycle (ISCC) system, in terms of thermal efficiency, electricity production and levelized electricity cost (LCOE). During the day light the power plant operates as an ISCC and operates as a conventional combined cycle (CC) during the night or cloudy days. In one hand the obtained results show that at the design point the solar electricity ratio may reach about 17 % and the global thermal efficiency 63 %, leading to lower fuel consumption and carbon emission. On the other hand, the economic assessment depicts that LCOE may reach 0.0222 $/kWh, which is about 28 % higher than that of (CC) power plants. Furthermore, by introducing the environmental effect LCOE becomes equal to 0.0272 $/kWh which is higher. Therefore, the annual solar contribution relatively to this ISCC installation site will allow about 18.45 million $ of fuel saving, avoiding emission of 0.89 million ton of CO2 over 30 years operation.

Effective and reliable ways to generate renewable energy is crucial for reducing global carbon emission in the ongoing battle against the climate crisis. Currently, low-temperature waste heat accounts for more than half of the rejected waste thermal energy produced in the United States. Traditional waste heat recovery methods such as steam cycle and thermoelectrics fall short at low temperatures due to uneconomically low conversion efficiency. The electrochemical conversion of heat to electricity, or thermogalvanic energy conversion, had been investigated for decentralized low-temperature applications. Traditional thermogalvanic cells were capable of harvesting thermal energy from spatial temperature gradients similar to thermoelectric plates. Lately, novel thermogalvanic devices had also been devised to harvest energy from cyclical temperature fluctuations through a technique known as Thermally Regenerative Electrochemical Cycle (TREC). In particular, the charging-free TREC cell could passively generate energy through no other external input than ambient temperature fluctuations. Thermogalvanic cells typically suffered low conversion efficiency and low open-circuit voltage due to a plethora of limitations. The motivation of this work was therefore to construct a highly-efficient thermogalvanic cell that could also produce high potential for practical applications. In this work, a charging-free TREC thermogalvanic cell based on Nickel Hexacyanoferrate was conceptualized, designed, and built. Owing to NiHCF's competitive temperature coefficient and gravimetric capacity of -1.0 mV/K and 60 mAh/g, the resultant charging-free cell achieved a full-cell temperature coefficient of -2.0 mV/K and a conversion efficiency of 9.33% relative to the Carnot limit. Furthermore, the practicality and manufacturability of the cell was verified through electronic integration testing and flexible cell fabrication.

Abstract:
Fossil fuels dominate the world energy supply today and the transport sector is no exception. Renewable alternatives must therefore be introduced to replace fossil fuels and their emissions, without sacrificing our standard of living. There is a good potential for biofuels but process improvements are essential, to ensure efficient use of a limited amount of biomass and better compete with fossil alternatives. The general aim of this research is therefore to investigate how to improve efficiency in biofuel production by process development and co-generation of heat and electricity. The work has been divided into three parts; power cycles in biofuel production, methane production via pyrolysis and biofuels from renewable electricity. The studies of bio-based methanol plants showed that steam power generation has a key role in the large-scale biofuel production process. However, a large portion of the steam from the recovered reaction heat is needed in the fuel production process. One measure to increase steam power generation, evaluated in this thesis, is to lower the steam demand by humidification of the gasification agent. Pinch analysis indicated synergies from gas turbine integration and our studies concluded that the electrical efficiency for natural gas fired gas turbines amounts to 56-58%, in the same range as for large combined cycle plants. The use of the off-gas from the biofuel production is also a potential integration option but difficult for modern high-efficient gas turbines. Furthermore, gasification with oxygen and extensive syngas cleaning might be too energy-consuming for efficient power generation. Methane production via pyrolysis showed improved efficiency compared with the competing route via gasification. The total biomass to methane efficiency, including additional biomass to fulfil the power demand, was calculated to 73-74%. The process benefits from lower thermal losses and less reaction heat when syngas is avoided as an intermediate step and can handle high-alkali fuels such as annual crops. Several synergies were discovered when integrating conventional biofuel production with addition of hydrogen. Introducing hydrogen would also greatly increase the biofuel production potential for regions with limited biomass resources. It was also concluded that methane produced from electrolysis of water could be economically feasible if the product was priced in parity with petrol.

Abstract:
Desenvolvida no âmbito da linha de pesquisa Metrologia para Energia, a presente dissertação de mestrado tem como objetivo validar os benefícios da tecnologia da termoacumulação como alternativa técnica e economicamente viável para deslocamento de cargas elétricas em períodos de grande utilização. O projeto de pesquisa teve como motivação o estudo de alternativas tecnológicas para viabilizar tarifas diferenciadas. A metodologia utilizada incluiu a revisão da literatura especializada sobre regulação tarifária e termoacumulação; desenvolveu estudos de sistemas de distribuição subterrâneos e aéreos situados em regiões de grande demanda de energia elétrica no horário comercial e desenvolveu análise de sensibilidade técnico-econômica visando a proposição de alternativas tarifárias e políticas de deslocamento de carga. O trabalho se desenvolveu no contexto da segunda revisão tarifária do setor elétrico, que busca repartir os ganhos de eficiência obtidos pelos agentes do setor elétrico com os seus consumidores. Dentre os resultados do trabalho destacam-se: (i) a comprovação da viabilidade da aplicação da termoacumulação em sistemas de climatização, (ii) a redução de custos de operação e implantação de subestações de energia elétrica para consumidores de sistemas de refrigeração e (iii) e proposição de uma tarifa diferenciada que permite a mudança do perfil de carga de sistemas de refrigeração comerciais. Estudos realizados mostraram que a termoacumulação pode gerar redução dos custos de energia elétrica da ordem de 30 a 45 por cento. Como conclusões, o trabalho reconhece a importância de se implantar políticas que privilegiem novas alternativas tarifárias e ressalta os benefícios que resultam da adoção dessa tecnologia alternativa para o meio ambiente.
Studies have shown that thermo-accumulation is an attractive technology to increase the electric power load factor which can lower tariff billings in electricity retailing (30-45 percent), the motivation for this research project. The aim of the present M.Sc. dissertation is to validate the technological benefits of thermo-accumulation applied to the electric sector as an economically feasible alternative for power load displacement at peak mode. The methodology included a literature survey on tariff billings and the regulation of the electric sector; a study of aerial and underground distribution systems at locations of high power load demand; a technical-economic analysis (consumption and tariff) of power substations. Developed within the context of tariff billing revision where the electric sector shared energy-efficient gains with customers, the research project suggests alternate tariff schemes and power load displacement policies. Three major results were found: (i) the feasibility of thermo-accumulation in acclimatization; (ii) the reduction of operational cost of electricity for commercial air-conditioning users; (iii) a proposal for differentiated retailing tariff billings. To highlight the conclusions of the work, the use of the thermo-accumulation technology by electric companies was shown to be unmistakable. On the one hand it provides better tariff schemes for consumers and on the other it is environmentally friendly.

Abstract:
Luossavaara-Kiirunavaara Aktiebolag (LKAB) är en gruvdriftskoncern med järnmalmsbrytning som huvudsaklig verksamhet. En av produkterna tas fram genom att raffinera järnmalm till pellets vilket är en efterfrågad produkt vid ståltillverkning.   Vid sintring av råkulor till pellets är temperaturen väsentlig för att få så hög oxidation som möjligt av magnetit till hematit och för att få rätt fasthet. För att reglera värmen bör temperaturen mätas bland råkulorna eftersom det är kulornas temperatur som är det viktiga.                                   Projektet går ut på att undersöka möjligheterna att mäta temperatur bland råkulor på gratevagnar som åker genom en pelletsugn med ett permanent mätsystem. Här ställs höga krav på mätsystemet på grund av miljö, portabilitet och drifttid. Miljöanalyser gjordes för att ta reda på vilken påfrestning ett mätsystem bör klara av. Förslag om placering av mätutrustning framtogs genom kartläggning av miljön. En värmeundersökning utfördes av vad hög värme har för påverkan på elektroniska komponenter som kan behövas till ett mätsystem. Det gjordes även en undersökning över vilka komponenter som kan klara av den värme ett mätsystem kan bli utsatt för. Utifrån detta kunde ett prototypmätsystem konstrueras för att mäta temperaturen där ett mätsystem kan placeras på en gratevagn samt för att skapa möjlighet för mätningar med termoelement i bädd. Mätsystemet skapades med trådlös kommunikation, möjlighet till loggning av data och med möjlighet att ansluta tre termoelement av typ S. Olika typer av trådlös kommunikation utvärderades för att se vad som kan vara mest lämpat med tanke på miljö, räckvidd, strålning och strömförbrukning. Strömförsörjning undersöktes för att hitta den mest lämpade strömförsörjningen med längst drifttid och högst funktionalitet. En utredning gjordes för att hitta monteringsmöjligheter av ett mätsystem på en gratevagn. Värmeavskärmning och isolering undersöktes för att få ner temperaturen i kapslingen och för elektroniken i ett mätsystem. Några olika temperaturgivare granskades för att hitta en som klarar av att mäta temperaturer upp till 1500°C och som fysiskt kan monteras på en gratevagn.
Luossavaara-Kiirunavaara Aktiebolag (LKAB) is a mining group with iron ore mining as the main business. One of the products is produced by refining iron ore to iron pellets, which is a quality and environmentally clever product  in steel production.                                     When iron pellets are produced by roasting green pellets the temperature is very important. The goal is to get as much oxidation as possible from hematite to magnetite and to get correct mechanical properties. To control the process it’s important to know the temperature of the green pellets specifically and not the surrounding mechanical structure, ceramics lining in the furnace and the influence from radiation.   The goal of the project is to examine possibilities to measure temperature with a permanent measurement system of green pellets which are transported on grate cars trough pellet plant. The measurement system has to meet some requirements of environment, portability and operating time. Analysis of the environment has been made to get specification of what a measurement system has to withstand. Proposition about assembly location has been investigated by analysis of the environment. A thermal analysis has been made of electronic components, especially electronic components that can be used in a measurement system. A analysis has also been made of which electronic components that are suited for a measurement system and can withstand the heat. A development measurement system has been developed from the results of the analysis. The system has been constructed to measure the temperature of what a system can be exposed of on a grate car. This with wireless and data-logging support and future measurements possibilities with three thermocouples of type S.   Wireless data transfer was examined to see what type is most suited for the task with knowledge of environment, transmission range, radiation and power consumption. Power sources was examined to find a power source with longest working time and highest functionality. Heat insulation and reflective materials has been investigated with the goal to get the temperature in the system enclosure as low as possible. Some different types of temperature sensors that can measure temperatures up to 1500°C and which can be mounted on a grate car has been evaluated.

Abstract:
The availability of cost effective storage capacity is considered essential for increasing the share of renewables in electricity generation. With the development of solar thermal power plants large thermal storage systems have become commercial in recent years. Various storage concepts are applied, systems using solid storage media are operated at a maximum temperature of 680 °C, other systems using molten salt as storage medium show thermal capacities in the GWh range. Heating these storage systems directly by surplus electricity and using the heat later during the discharge process to operate turbines is not very attractive, since the process is limited by the Carnot efficiency. Alternatively, surplus electricity can be used to transform low temperature heat into high temperature heat which is stored in a thermal storage system during the charging process. During discharge, this heat is used to drive a turbine generating electric energy. Theoretically, this concept allows a roundtrip efficiency of 100%. Various options for the implementation of this storage concept have been suggested, using air or CO2 as working fluids. Recently, DLR has demonstrated the operability of a latent heat storage system connected to a steam circuit at 100 bar. The availability of this latent heat storage technology allows new implementations of the storage concept based on heat transformation. Using a left-running Rankine cycle during the charging process, heat from the environment is used to evaporate steam, which is compressed using the surplus electricity. Superheated steam exiting the compressor flows through the thermal storage system composed of latent heat storage sections and sensible heat storage sections. After throttling, the water enters the evaporator again. During discharging, heat from the storage system is used to evaporate and superheat steam, which drives the turbine. A cascaded implementation of this concept, using ammonia for the low temperature part of the process, while water is used for the high temperature part, reaches a storage efficiency of 70%. The integration of low temperature waste heat sources allows the compensation of losses.

Abstract:
Abstract Thermo-acoustic technology offers the possibility to convert heat energy into a sound-wave that can potentially be used to generate electricity through a linear alternator. The construction of a two-stage traveling-wave thermo-acoustic generator is described in this paper. The potential of conversion of heat into electricity has been investigated experimentally. The effect of the geometrical configurations of the thermo-acoustic system on its performance has been analyzed. The two thermo-acoustic engine cores were tested separately and subsequently combined to build a two-stage system. Two different configurations of engine cores have been considered namely series and parallel configuration. Hence, the effect of the orientation of the engine core has been investigated to get an insight into its effect on the output of the device. Parallel arrangement was found to be the most efficient configuration. An onset time of 3.15 minutes was recorded for the device to generate a sound wave. This system has achieved 125.7 dB corresponding to an output voltage of 486 mV. This study guides the development of more efficient electricity generators using thermo-acoustic technology.

Abstract:
Abstract This work describes the design and construction of a four-stage traveling-wave thermo-acoustic system for electricity generation. The thermo-acoustic conversion consists of using a sound-wave for the transfer of heat from a low to high-temperature medium or the use of heat energy to generate a sound wave. Both the absence of moving parts and the simplicity of thermo-acoustic systems make the technology sustainable for converting low-grade waste heat into acoustic power. Many existing studies have pointed out the acoustic-to-electric potential of thermo-acoustic systems. Hence in this work, a thermo-acoustic system has been developed. The traveling-wave system has a total length of 3 560 mm. The distance between each thermo-acoustic engine is 640 mm. Each engine stage had four cartridge heaters used to generate the heat required. A commercial loudspeaker was used to convert sound into electricity. The minimum temperature difference necessary to induce a voltage at the terminals of the loudspeaker was approximately 200°C. The four-stage traveling-wave system generated the highest output voltage of 4.218 V.
